The literature review examines the role of iconic and journalistic images in the collective memory of historic events. The dynamic interplay of collective memory and images forms the theoretical backbone of the thesis, which applies semiotic analysis to interpret the meaning and significance of three significant photographs from the festivals. Results indicate that photographs from the original festival are icons forming the template against which photographs from later festivals can be understood and read. Images from anniversaries of the festival reflect a ritualistic repetition of themes from the original festival, as well as its increasing commercialization. / Committee in Charge: Dr. Julianne Newton, Chair; Dr. Pat Curtin; Dr. Philip Scher
